I suggest not doing it. I have never heard of "a girl with straight ears leans on her ears". Girls are born with straight ears. And there are many acupuncture points on the ear. I hope not to use bandages, which will affect blood circulation and cause headaches. 15 years old, still in the development stage, not good for health. If you think it is really ugly, just cover it with your hair. Ears are made of cartilage and have a relatively fixed shape. If you don't do some minor treatment (surgery) at the root of the ear, it is difficult to become partial to the ear.
